I need help with 12 and 13 please

Answer:
number 12
4 will fit
number 13
60 will fit
Step-by-step explanation:
number 12 you change both to cm^2
by first changing 1m to cm then multiplying you will get 10000cm^2 and for 50 × 50 cm you will get 2500 when you divide 10 000 by 2500 you get 4
number 12
since we know that 2500 cm^2 is 50×50 cm we can change that to metres we will get 0.5 we then multiply 0.5×0.5 we will get 0.25 if we divide that into 15 we will get 60
